Abstract
A coupling joint for thermoplastic hose comprising a nipple having annular ribs of approximately the same diameter as the hose I.D., for easy insertion into the hose, and a nut of rigid material threaded over the hose O.D. and radially opposite the ribs. The nut has a rounded tapered thread that deforms the hose material to fill the thread and to cause the I.D. of the hose to fill the spaces between the annular ribs. The nipple has a cylindrical portion at its end and the nut has a counterbore at its forward end and the hose is lightly gripped therebetween to avoid sudden stress concentration on the hose at the first rib.
